PlaneConnection delivers notifications through multiple channels for safety events, trip updates, crew changes, FBO activity, billing, and compliance deadlines.

​
Available Channels

Four notification delivery channels are available, each suited to different urgency levels.
ChannelProviderDelivery SpeedBest For
EmailResend (primary), SendGrid (fallback)Near-instant (typically < 30 seconds)Detailed notifications, records that need archival, compliance communications
SMSTwilioNear-instant (typically < 10 seconds)Critical alerts requiring immediate attention, time-sensitive crew notifications
PushWeb Push APIInstant (when browser/app is active)Real-time updates, status changes, assignment notifications
In-AppNative (WebSocket)InstantLow-urgency updates, informational messages, activity feed items

​
Channel Fallback Behavior

If a primary channel fails, the system falls back according to these rules:
FailureFallback
Email delivery failure (bounce)Retry once after 5 minutes, then log as undeliverable
SMS delivery failureFall back to email, log SMS failure
Push not available (user offline)Queue for delivery when user reconnects; also deliver via in-app
In-app (user not connected)Queue in notification center for next session
SMS notifications require a verified phone number on the user’s profile. Users without a phone number on file will not receive SMS notifications, and the system falls back to email for those events.
